please help me with these two math questions

Question

To get the 10% discount, a shopper must spend at least $200.

Use d to represent the spending (in dollars) of a shopper who gets the discount.

Ivanna exercises no less than 40 minutes per day.

Use t to represent Ivanna's amount of exercise (in minutes per day).

Answer 1

This response is probably too late to be of use, but for future reference for these types of problems, I can explain these two for you.

For the first problem, we need to build an inequality that represents the amount of spending needed to get the discount. Since a shopper must spend at least $200, we know that d has to be greater than or equal to $200. It can't be less than $200, but it can be the same or more. Now it's time to set up the inequality that shows that: d > 200. As I mentioned, d has to be the same or more than 200. This is why we used a greater than or equal sign in the inequality.

This same process is required for the second question. So, Ivanna exercises (t) no less than 40 minutes a day. Meaning she exercises 40 minutes or more. This tells us that t has to be greater than or equal to 40. Now it's time to set up an inequality that shows that t is greater than or equal to 40: t > 40.
